Sierra Leone appointed its first chief innovation officer, Moinina David Sengeh, to head the Directorate of Science, Technology, and Innovation - operating within the office of the President.

Sengeh, who is 31, studied at Harvard and MIT for his Ph.D. where his thesis focused on improving prosthetic comfort for amputees. He's also working with IBM Research Lab in Nairobi focusing on the design and deployment of healthcare technologies in Africa. You can watch his 2014 TED talk here.
